Definitions

  • the invention relates to a plastics processing machine and a method for quickly converting the plastics processing machine from a first product form to a second product form.
  • Such a plastic processing machine can be, for example, an injection molding machine or a blow molding machine; Such plastic processing machines are generally known.
  • This object is achieved according to the invention in a plastics processing machine with a two-part mold, the mold halves of which are attached to two mold platens that can be moved apart, in terms of process technology, in that the mold halves of the first product mold remain on the mold platens and the mold halves of the second product mold are clamped onto the remaining mold halves of the first product mold.
  • the molten plastic raw material to be processed and / or the resources such as e.g. electrical energy, hydraulic oil or cooling water, supplied by means of changeable pipelines and / or flexible (hose) lines or cables and, if necessary, discharged again.
  • the mold halves of the first product mold clamped on the mold mounting plates have additional fastening means on their inwardly facing sides for clamping the mold halves of a second product mold.
  • the machine can continue to be operated without changing the program if a fixed adjustable spacer is provided in the closing path of the horizontally displaceable mold halves, so that the machine parts or mold clamping plates which can be moved apart are at a limited, freely selectable distance can be moved together in a defined manner.
  • molten plastic and / or operating materials such as e.g. Hydraulic oil or cooling water changeable pipelines or flexible hose lines or power cables, if necessary with quick fasteners (e.g. bayonet fasteners) or plug connections are provided.
  • the blow mandrel can be adapted quickly to another product blow mold in a blow molding machine by placing an extension piece on the blow mandrel.
  • the blow molding machine 10 comprises a base frame 34 and a vertical support 36, to which the hydraulic drives for moving the mold mounting plates 16, 18 are essentially fastened in the horizontal direction.
  • An upper horizontal support 38 and a lower horizontal support 40 are provided for guiding the mold mounting plates 16, 17.
  • the mold halves of the product or plastic hollow body to be blown are usually attached to the mold mounting plates 16, 18. In the case of complicated product forms with undercuts such as flange rings on barrel bodies or molded handles on canisters, the mold halves can each be provided with separately displaceable mold slides.
  • the mold halves 12, 14 clamped here on the mold mounting plates 16, 18 are designed for a 220 1-tonne drum. This first product shape is shown in dashed lines in the two mold halves 12, 14.
  • the mold halves 12, 14 are provided at the top and bottom with mold slides for upsetting the circumferential carrying and transport rings.
  • the mold halves 12, 14 of the first product mold are now provided with fastening means 20, such as, for example, angle irons with threaded holes, for clamping two mold halves 22, 24 of a second product mold.
  • the mold halves of the second product form are 60 1 plastic canisters are provided and each have a shaped slide at their lower ends for compressing a handle in the canister wall.
  • the displaceability of the mold slides is indicated by two vertical arrows and the movability of the mold halves or mold clamping plates by a horizontal arrow.
  • the blow mandrel 32 suitable for the large-volume barrel is provided with an adapted extension piece 30 for the canister blow mold halves 22, 24, which also have corresponding fastening means.
  • a fixed adjustable spacer 26 is provided on the lower horizontal support 40, by means of which the moving machine parts can be easily adapted to the additional mold halves.
  • the blow mold halves are each provided in the usual way with hydraulic lines - for actuating the mold slides - and coolant lines.
